Submit Form Question

[quinnipiac0807]

I have a form, and when I click the Submit button I get this error.

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Line 132: projecttask.ProjectDescID = Convert.ToInt32(ddlProjectDesc.SelectedItem.Value);

The code on line 132 is where I get the error, but line 131 works fine. Does anyone have any idea why this is doing this or have any suggestions?

Thanks in advance

Have you debugged it?
It seems to me that one of projecttask.ProjectDescID, ddlProjectDesc.SelectedItem or ddlProjectDesc.SelectedItem.Value is null...
If so, try to see why and where it happens. Most common mistake: an object was not initialized.
